Sorry man, what lines are you talking about? Don't see any in the picture other than what looks to be the grain of the anti-glare coating.

Zoom the photo large, and you'll see bright-dim-bright-dim scan line effect every other pixel row.
It's a panel issue, on some runs of LCD panels.

(I'm familiar with this artifact -- it affects one of my two LightBoost monitors, and only at the upper-right corner. My VG278H has none of this artifact, while it effects the upper-right corner of my XL2411T)
